On Supergravity Solutions of Branes in Melvin Universes
Mohsen Alishahiha, Batool Safarzadeh, Hossein Yavartanoo
We study supergravity solutions of type II branes wrapping a Melvin universe. These solutions provide the gravity description of non-commutative field theories with non-constant no…

Semi-classical Probe Strings on Giant Gravitons Backgrounds
M. Alishahiha, H. Ebrahim, B. Safarzadeh +1
In the first part of this paper we study two symmetries of the LLM metric, both of which exchange black and white regions. One of them which can be interpreted as the particl…

On the Seiberg-Witten map of SYM theory in Non(anti)commutative Harmonic Superspace
Batool Safarzadeh
We consider supersymmetric U(1) gauge theory in a nonanticommutative harmonic superspace with the singlet deformation. We generalize analytic superfield a…
